Mizusui

Mizusui is a Japanese term that means "living portion" or "live vein" in relation to bonsai. It refers to the living parts of a trunk on shimpaku (Sargent's juniper) and tosho (Japanese needle juniper) trees that have bleached and withered tree tops or branches . Mizusui is important for the health and survival of these trees, as it carries water and nutrients from the roots to the foliage.
